One in five cyclists in London said they have stopped cycling to work following the recent deaths, and almost 70 per cent believe that it is not safe to cycle on the capital’s roads, according to a poll.

The survey for BBC London was carried out to determine what effect last month’s spate of six deaths in two weeks had on riders’ attitudes and behaviour.

The Com Res poll of 1,000 Londoners — a quarter of whom said they were cyclists — found that 20 per cent of cyclists said they had stopped cycling to work and 68 per cent thought that it was not safe to cycle on London’s roads.
